)Parameters
- startRow Int32
- Index of the first row of the sub-matrix.
- endRow Int32
- Index of the last row of the sub-matrix.
- rowStride Int32
- The increment for the row index in the original matrix corresponding to an increment of one in the row index of the new matrix.
- startColumn Int32
- Index of the first column of the sub-matrix.
- endColumn Int32
- Index of the last column of the sub-matrix.
- columnStride Int32
- The increment for the column index in the original matrix corresponding to an increment of one in the column index of the new matrix.
- transposeOperation TransposeOperation
- A TransposeOperation value that specifies whether or not this view should show the transpose of the matrix.
- intent Intent (Optional)
- An Intent value that specifies the intended use of the sub-matrix.
Return Value
Matrix<T>A Matrix<T> that contains the specified rows and columns.
Remarks
The matrix returned by this method is a view on the original matrix. This means that any changes to the elements of the return value will cause the corresponding elements in the original matrix to change as well. Use the CloneData() or the ToDenseMatrix() method on the return value to create a matrix which has its own private element storage independent from the original matrix.
Exceptions
| Argument | startRow is less than zero or greater than or equal to the number of rows. -or- endRow or endRow is less than zero or greater than or equal to the number of rows. -or- startColumn is less than zero or greater than or equal to the number of columns. -or- endColumn or endRow is less than zero or greater than or equal to the number of columns. |
